Airport Extreme firmware 7.6 breaks VLAN bridging
I live in France and I'm a subsriber of the ISP "Free".
This ISP provides with a DSL router "Freebox ADSL" and an IPTV box "Freebox HD"
The link from the router box to the IPTV box is either Wi-Fi or Ethernet.
I choosed to use Ethernet.
I have the current setup:
DSL router ---- Airport Extreme (bridge mode) ---- Computers & a basic GE switch ---- IPTV box.
This setup worked just fine for years, until I recently updated to firmware 7.6 on the Airport Extreme.
The IPTV box would no longer start, if connected directly to the DSL router, it starts just fine.
After some tests and searching, I finally found that the two boxes are talking to each other over a dedicated VLAN (VLAN 100).
And it seams that version 7.6 is now filtering the ethernet packets with VLAN information.
Reverting to 7.5.2 solves the issue instantly.
Upgrade again to 7.6 brakes my IPTV immediatly.
Anyone has any idea ? Any hidden setting or tweak to restore VLAN bridging in 7.6 ?
